For all the pressures and rewards of regionalization and globalization, local identities remain the most deeply impressed. Even if the end result of globalization is to make the world smaller, its scope seems to foster the need for more intimate local connections among many individuals. As Bernard Poignant, mayor of the town of Quimper in Brittany, told the Washington Post, “Man is a fragile animal and he needs his close attachments. The more open the world becomes, the more ties there will be to one's roots and one's land.”

    In most communities, local languages such as Poignant's Breton serve a strong symbolic function as a clear mark of “suthenticity（原真性）”. The sum total of a community's shared historical experience, authenticity reflects a perceived（感知到的）line from a culturally idealized past to the present, carried by the language and traditions associated with the community's origins. A concern for authenticity leads most secular（世俗的）Israelis to champion（捍卫，维护）Hebrew among themselves while also acquiring English and even Arabic. The same obsession with authenticity drives Hasidic Jews in Israel or the Diaspora to champion Yiddish while also learning Hebrew and English. In each case, authenticity amounts to a central core of cultural beliefs and interpretations that are not only resistant to globalization but also are actually reinforced by the “threat” that globalization seems to present to these historical values. Scholars may argue that cultural identities change over time in response to specific reward systems. But locals often resist such explanation and defend authenticity and local mother tongues against the perceived threat of globalization with near religious eagerness.

    As a result, never before in history have there been as many standardized languages as there are today: roughly 1,200. Many smaller languages, even those with far fewer than one million speakers, have benefited from state-sponsored or voluntary preservation movements. On the most informal level, communities in Alaska and the American northwest have formed Internet discussion groups in an attempt to pass on Native American languages to younger generations. In the Basque, Catalan, and Galician regions of Spain, such movements are fiercely political and frequently involved loyal resistance to the Spanish government over political and linguistic rights. Projects have ranged from a campaign to print Spanish money in the four official languages of the state to the creation of language immersion nursery and primary schools. Zapatistas in Mexico are championing the revival of Mayan languages in an equally political campaign for local autonomy（自治权）.

    In addition to causing the feeling of the subjective importance of local roots, supporters of local languages defend their continued use on practical grounds. Local tongues foster higher levels of school success, higher degrees of participation in local government, more informed citizenship, and better knowledge of one's own culture, history, and faith. Government and relief agencies can also use local languages to spread information about industrial and agricultural techniques as well as modern health care to diverse audiences. Development workers in West Africa, for example, have found that the best way to teach the vast number of farmers with little or no formal education how to sow and rotate crops for higher yields is in these local tongues. Nevertheless, both regionalization and globalization require that more and more speakers of local languages be multi-literate.

    In this Pennsylvania city, Pittsburgh is shrinking but getting wealthier. Since 2000, its population has declined by 95,000 while its income per capita (人均) has shot up 24 percent. The trend is taking hold in many other cities, like Buffalo in New York, Providence in Rhode Island and New Orleans.

    Some of these areas have created more high-paying jobs in energy, health care or education. Others have managed to reshape their producing industry for a new economy. Higher-paying jobs have a greater effect because they create demand for additional services. "The story in Pittsburgh is very positive, and other areas are looking at it as an example of the transformation that might be possible,” said Guhan Venkatu, who wrote an economic history of the area called “Rust and Renewal” for the Federal Reserve Bank of Cleveland.

    Carnegie Mellon University and the University of Pittsburgh have helped bring tech jobs and innovation(革新) to the area by sponsoring tech centers that help graduates start companies without moving to Silicon Valley or San Francisco. This has helped keep Pittsburgh's educated young population growing even as the entire population in the city has dropped.

    Pittsburgh has more STEM (science, technology, engineering and math) jobs than other shrinking cities, about 80, 000 or 7% of all jobs. STEM jobs add productivity and income growth to the area. Manufacturers of high-tech medical equipment in the Pittsburgh area also have doubled employment in the last 10 years.

    However, some experts question whether growing income per capita can really make up for a declining population. According to Patrick Adler, a researcher at the University of Toronto, population loss does matter if it means lower-skilled workers have fled because of a lack of opportunity. What's more, high-paying jobs in education and health care can disappear if the population declines too greatly. So it'd be wise to find ways to increase the population.

    Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (减法).

    Solving math problems requires a complex level of involving the mental management of numbers, long-term rules and short-term working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.

    RMIT's Professor Adrian Dyer said numerical (数字的) operations like addition and subtraction are complex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your long-term memory, while mentally using skillfully a set of given numbers in your short-term memory,” Dyer said. “On top of this, our bees also used their short-term memories to solve arithmetic problems, as they learned to recognize plus or minus as abstract concepts.”

    The findings suggest that advanced numerical cognition (认知) may be found much more widely in nature among non-human animals than previously suspected.

    “If math doesn't require a massive brain, there might also be new ways for us to include interactions of both long-term rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.

    Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more complex level of processing.

    Previous studies have shown some primates (灵长目动物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.

Internet Time Tied to Teen Depression(抑郁) Symptoms

    Spending time online is normal behaviour for teenagers. But too much Internet use by teens —or too little, for that matter —might be related to depression, a new study finds.

    The findings, reported in the journal of Pediatrics, do not mean that the Internet is to blame. For one, teens in the study who spent no time online were also at increased risk of depression symptoms. Instead, the researchers say that both heavy Internet use, and non-use, could serve as signals that a teenager is having a hard time.

    For the study, Dr Pierre-Andre Michaud and his colleagues at the University of Lausanne, Switzerland, surveyed 7,200 individuals aged 16 to 20 about their Internet use.

    Those who were online more than two hours per day were considered "heavy" Internet users, while those online anywhere from several times per week to two hours per day were considered "regular" users.

    The teenagers also answered a number of health-related questions, including some standard questions about "depressive tendencies" that gauge (判定) how often a person feels sad or hopeless. Compared with regular Internet users, the study found, kids who were heavy users or non-users were more likely to be depressed or very depressed.

    Among male teens, heavy users and non-users were both around one-third more likely to have a high depression score, compared to "regular" users. Among girls, heavy Internet users had an 86 percent greater chance of depression, while non-users had a 46 percent greater likelihood compared to regular users.

    That was with factors like family income and any chronic health problems taken into account. Since teenagers typically go online to contact friends, the researchers guess that those who are never online may be more socially isolated.

    My son Leon's passion for surfing began at the age of 13. After school each day, he put on his wet suit, paddled out beyond the surf line and waited to be challenged by his companions.

    One afternoon, the lifeguard reported over the phone to my husband Wilson that Leon's eye was badly injured by his board. Wilson rushed him to the emergency room. He received 26 stitches (缝针) from the corner of his eye to the bridge of his nose.

    I was on an airplane flying home. Wilson drove directly to the airport after they left the doctor's office. He greeted me at the gate and told me Leon was waiting in the car.

    "Leon?" I questioned. I remember thinking the waves must have been terrible that day.

    "He's been in an accident, but he's going to be fine."

    A traveling working mother's worst nightmare had come true. I ran to the car so fast that the heel of my shoe broke off. I swung open the door, and my son with the patched eye was leaning forward crying, "Oh, Ma, I'm so glad you're home."

    I cried in his arms telling him how awful I felt about not being with him.

    "It's okay, Mom," he comforted me. "You don't know how to surf anyway."

    "What?" I asked, confused by his logic.

    "I'll be fine. The doctor says I can go back in the water in eight days."

    I wanted to tell him he wasn't allowed to go near water again until he was 35, but instead I bit my tongue and prayed he would forget about surfing.

    For the next seven days he kept pressing me to let him surf again. One day after I had repeated "No" to him for the 100th time, he beat me at my own game.

    "Mom, you taught us never to give up what we love."

    I gave in.

    Back then Leon was just a boy with a passion for surfing. Now he ranks among the top 25 professional surfers in the world.
